Shot at home on a bright red tulip. Converted to black-and-white for clarity. Can you spot a teeny-tiny aphid in the picture? You may wish to see this picture in a larger size on Flickr by clicking on the photo.

Also known as christmas cactus (but it is flowering here in Cambridge just in time for Thanksgiving), Schlumbergera’s are a strange sort of cactus plants. They have stems that look like leaf-like pads connected to one another. The flowers form at the terminal end of the plant. I grew mine from a small two segment section taken from a friends house and popped into a pot.
